Hey,
Any company (and specially if they are publicly traded) needs capital (money) from investors (banks for example) and other sources to survive & thrive. They need this extra money to invest in M&A, Turnaround, new product launch, R&D and other things-hope you get the point.
Getting capital cheaply is important- this means lower return expectations compared to peers as investors want the company to generate profits to pay them back. If the return expectations are higher, overall returns for the company will reduce. Amazon is a greatest example of a company that has access to huge amounts of cheap capital with much lower return expectations. Read about this..
So if a company doesnt have access to capital (and cheap capital) how are they doing to get the money to do what they want to do?! There are other ways to raise but most aren't sufficient- selling assets, carve-outs etc.
Hope that helps. Use frameworks loosely to give you a head start but dont get bogged down them.
